Abstract

[Purpose/ significance]To clarify the professional skill demand and change trend of high-tech enterprises from the perspective of supply and demand optimization is helpful to accelerate the aggregation of innovation elements, gradually establish technical groups and establish a sound cooperation system. [Method/process]Based on the resume information of incumbents in the Integrated Circuit（IC）field, the collaborative filtering recommendation algorithm in the ime dimension was used to predict and evaluate the relationship between enterprises and professional skills in the field. By combining Word2vec word vector model and LDA model, data mining and corpus expansion of resume information are carried out to identify skill topics. Then describe the evolution path of skill theme and carry out visual expression to clarify the development status and evolution law of skill theme in IC field. [Result/conclusion]The research shows that the collaborative filtering idea based on time dimension is suitable for the prediction of the relationship between enterprises and skills, with an average accuracy of 96.68%. The evolution of skill theme in IC field shows the trend of "aggregation→dispersion→reaggregation", and the evolution law of each skill theme path is different, which is embodied in spiral cross evolution, innovation iterative evolution and technology dependency evolution. The overall skill development trend and path change law of IC industry given by the study can provide more accurate retrieval methods and skill selection directions for high-tech enterprises and incumbents.
